Traffic Congestion
The Scottish Household Survey Travel Diary shows that around 12 per cent of drivers felt that their journey was delayed due to congestion. In 2006, 12.8 per cent of drivers had experienced delays due to congestion.
This is based on drivers' own perception of whether or not their journeys by car were delayed due to congestion, regardless of the journey type, purpose or the nature of the roads they travelled on. Reductions in congestion enable shorter and more reliable journey times, contributing to improved productivity and economic growth.
Each year's figure is based on a sample of around 14,000 journeys reported by car drivers, a change of +/- 0.6 percentage-points or more is statistically significant.
The Scottish Government has established a National Indicator to reduce the proportion of driver journeys delayed due to traffic congestion.
